After further digging around and testing the game I can confirm that its somewhat easy to crash the game by changing through resolutions and toggling the fullscreen option.
I was also able to find a lot sources with people having issues in general that their monitors go black after quitting a game so dont worry about that one too much. Probably not your fault.
The only (unreliable) hint I found was to replace the d3d9.dll file. who knows where the bug actually is that causes this behavior.
One last thing...
Why is the list with possible resolutions so long and includes duplicates of the same resolution every once in a while?
